Specification of Letters Patent. Patented J 113 1'7, 1919,

Application filed August 12, 1918. Serial No. 249,555.

To all whom it may concern:

Be it known that I, CARL OSCAR LIND- GREN, a citizen of the United States, residing at Sanborn, in the county of Barnes and State of North Dakota, have invented certain new and useful Improvements in Grain- Shockers, of which the following is a specification.

This invention relates generally to shockers, and particularly to attachments. to be used in connection with bindery machinery, having for its primary object to generally simplify and improve the construction and operation of such devices, as well as to increase their practicability.v

The primary object of the invention is to provide a shocker to be positioned upon a binder in such position as to receive the bundles delivered from the binding machinery, and which may be easily and quickly actuated by the operator of the binder to compress the various bundles and to set the same upon the ground in upright position.

A further object of the invention is to provide a device of the character stated which is semi-automatic in operation, and which when initially operated by the binder mechanic will perform one after the other, a series of operations without the attention or guidance of the machine operator.

Still further objects reside in providing a machine of the character stated which shall be of extremely simple and inexpensive construction, which involves comparatively few parts, the various parts being so constructed, arranged and assembled as to minimize the opportunity for wear or breakage, and which will prove positive and accurate in operation.

With these objects in view, together with others which will appear as the description, proceeds, the invention resides in the novel formation, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings and particularly pointed out in the claims.

In the drawings Figure 1 is a top plan, parts broken away, of the improved shock forming device, and illustrating the same as applied to a conventional form of binder,

Fig. 2 is a front elevation of the devlce illustrated in Fig. 1, v

Fig. 3 is an enlarged fragmentary view showing the connection between the shock holding arm and its supporting frame,

Fig. 4: is a sectional view taken substantially upon line 4- 1 of Fig. 3, and

Fig. 5 is a transverse sectional view taken upon line 55 of Fig. 1.

Referring now more particularly to the drawings, 6 indicates the supporting frame for the improved shock forming and setting device, and this frame may be a part of the binding machine itself, or may be a supplemental frame attached to the body'of the binder.

The shock forming and setting device includes a cage indicated generally at 7, and this cage comprises the substantially U- shaped top and bottom members 8, connected by the vertically disposedrods 9. These bars connect the U-shaped members at their bight portions, and prevent the shock delivered to the former fallingforward'ly from the same. These U-shaped members have arms 10'projectingfrom one side thereof and these arms are pivoted in vertical alinement upon the frame or body of the binder. This particular arrangement of the cage allows the same to swing forwardly or rearwardly beyond the side of the binder. The lower U-shaped member 8 may have projecting rearwardly therefrom the tines 11 to prevent the shocksfalling from the cage whenthe device is in operation.

The bottom of the cage is closed by a fork-like member indicated generally at 12. This member comprises a cross bar 13 having secured thereto the outwardly projecting tines 14, and the cross bar 13 is supported at the outer end of a rotatable bar 15. It will be observed that this bar is connected to the cross bar at right angles to the latter and inwardly from the forward end of the same. The tines 14 are of a length equal to the distance between the arm portions of the U-' shaped members 8 so as to extend clear across the bottom of the cage. The inner end of the bar 15 is provided with a head. or ball 16 which fits within a'socket 17 secured to the frame 6, and an elongated slot 18 in the socket member permits of the arm' moving horizontally. The upper portion of the socket member 17 is provided with an arcuate opening 19 through which projects a pin 20 secured at its inner end to the ball 16. When the rod 15 is in such position that the outwardly projecting pin 20 is disposed horizontally,

the arm will lee-prevented from swinging with its ball as a pivot, as the pin 20 will engage the sides of the arcuate opening 19 and prevent such movement. l/Vhen the member 15 has been rotated, however, so that the pin 20 is vertically disposed, the arm will be permitted to rock with its ball as a pivot, as it will then rotate upon a vertical aXis. ment of the arm and fork is such that when the fork is in horizontal position, the rod 15 will be held against rocking or swinging movement but it will be understood that the said rod isat all times capable of rotating. When the rod has been rotated so the pin 20 is disposed vertically, the fork will be tilted so that matter contained therein will be dropped from the fork.

Arranged in longitudinal relation upon the frame 6isthe rotatable shaft 21. This shaft may be provided at one end with a sprocket wheel 22 over which passes a chain 23, the latter being operatively connected with a part of the running gear of the binder or the power mechanism of the latter. It will be understood that this shaft is constantly rotating during operation of the binder. The shaft has secured in spaced relation thereon, a pair of clutch sockets 24 and Y25, respectively, with which the heads 26 and 27 are designed to engage. The head 26 is of substantially frusto-conical shape and is designed to fit within the similarly formed aperture in. the head 24, being normally held disengaged with. the latter by the expansion spring 28. The outer end of the head 26 is equipped with a spool or roller.

portion 29, upon which a chain 30 is adapt ed to wrap. This chain passes over a guide roller 31 carried by frame 6 and is connected at its outer end near the outer extremity of the'rod 15. A lever 32 is pivoted upon'the frame .6 near the spool 29 and one end of this lever is designed to engage the spool to force the same so that the clutch head 26 will move into engagement with the head 24. The inner end of'the lever 32 is connected to a chain or cord 33, and the latter passes over a guide roller '34 on the frame 6. The inner extremity of this chain may be connected to a pedal 35, designed to be engagedby the foot of the machine operator. The construction is such, that when the pedal 35is d'epressed, the chain 38 will be tensioned sufliciently torcause the lever 32 to rock into engagement with the spool 29,--wl1ereupon' the frusto-conical head 26 willmove into frictional contact with the interior of the socket member 28. This action causes the rotary movement of shaft 21 to be transmitted to The construction and arrange- "The sliding head 27, is provided with teeth 36 adapted to engage with the socket member 25 to establish a positive connection between the socket member and the said clutch head. An expansion spring 37 is interposed between the head and socket to normally hold these elements separated. The head member comprises a spool as shown, to which one-end of a chain 38 is connected. This chain 38 passes over a guide pulley 39 and is connected at its outer end to the cage .7. The spool head 27 is capable of being slid longitudinally upon the shaft 21 by operation ofthe lever 40. Thislever is pivoted as shown upon the frame 6 and is controlled by pulling upon the cable or cord 41..

The cable 41 passes over suitable guide pulleys 42 and is connected at its inner. end to a pedal upon. the vehicle, in convenient reach to the operator. The cord 42 also has connected thereto a cord or cable 44, and the outer. end of this cable is connected to the pin 20 attached to the ball 16 at the inner end of the rotatable rod 15. It is obvious, therefore, that when pressure is applied to the pedal 43, the cord or cable 41 will be tensioned, whereupon the lever 40 will, be rocked forwardly to force the spool head 27 into engagement with the socket member 25. At the same time, the cord or cable 44 is tensioned, causing the arm member 15 to be rocked forwardly until the fork 12 has assumed the position indicated in dotted lines in Fig. 1. Immediately that connection is made between the clutch members 27 25, the spool rotates, causing the chain 38 to draw the cage inwardly and rearwardly, it being understood that the cage rocks upon its pivot. This rearward and inward swinging movement of the cage tensions the contractile spring 45. As soon as this rear-ward swinging movement. of the cage starts, the fork 12 tilts forwardly, causing the bundles lying therein to be brought into upright position and compressed between the fork member and the cage. When the fork has rotated to such degree that the pin 20 is 1n vertical position, the pedal '35 is depressed causing the head 26 to be frictlonally engaged with the socket member 28. This action causes the spool 29 to wind the cable or chain 30, causing the fork member to be swung rearwardly. This rearward swinging movement of the fork allows the bundles compressed between the fork and the cage to be deposited upon the ground 1n upright position. It will be observed that thefork is capable of being swung away from the underside of'the cage, thereby enabling the bundles to be precipitated upon the ground. As soon as the contents of the holder has been deposited, the pedals 35'43,will--be re leased and spring 45 will at once move the cage 7 to its outermost or initial position. The fork-12is returned to normal position by means of the contractile spring 46, and

by reason of the fact that the bar 15 is connected to the fork inwardly from one end thereof, the said fork will gravitate to normal or horizontal position. It will be understood that instantly upon release of ressure upon pedals 35 i3, the springs 28-37 will cause the clutch members upon the shaft 21 to become separated, thereby breaking the power connection.

From the foregoing, it is obvious that I have provided a shock receiving and depositing device which is of extremely simple construction and which will operate efficiently instantly upon application of pressure upon the pedals 3543. The tilting movement of the fork and the rearward swinging movement of the cage causes the bundles to be tightly compressed just prior to the depositing operation, and a perfect and composite shock is assured. By reason of the particular construction of the ball and socket and pin at the inner end rod 15, it is obvious that the latter is capable of swing ing with the ball of the pivot only when rotated a certain distance.

The foregoing description and the drawings have reference to what may be considered the preferred or approved form of my invention. It is to be understood that I may make such changesin construction and arrangement and combination of parts, materials, dimensions, etc., as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A grain shocker comprising a portable frame having a socket fixed to one side thereof, a cage supported by and disposed at one side of said frame, a fork closing the bottom of said cage and equipped with a rod projecting toward the said socket and having its terminal provided with a ball received within the said socket, the latter having a pair of openings therein, one of which receives the said rod, a pin secured to the ball and projecting through the other of the said openings, a flexible element secured to the said pin for moving the same, and mechanicalily operated means for swinging the said ro 2. A grain shocker comprising a portable frame, a cage supported by the frame, and comprising a pair of U-shaped members ar ranged in spaced relation, tines connecting said members, each U-shaped member having an arm pivotally connected at one end to the said frame, a fork disposed near one end of said cage and mounted to tilt and to move toward and away from said cage, and means for swinging the cage and moving said fork away, from the said cage simultaneously.
